24 # Kernel tags:
25 # Tags files are built in the top-level directory for each architecture,
26 # with a makefile listing the architecture-dependent files, etc. The list
27 # of common files is in ./Make.tags.inc. Links to the correct tags file
28 # are placed in each source directory. We need to have links to tags files
29 # from the generic directories that are relative to the machine type, even
30 # via remote mounts; therefore we use symlinks to $SYSTAGS, which points at
31 # ${SYSDIR}/${MACHINE_ARCH}/tags.
